19// VectorizedArray must be a POD (plain old data) type to make sure it
20// can use maximum level of compiler optimization.
21// A type is POD if it has standard layout (similar to a C struct)
22// and it is trivial (can be statically default initialized)
23// Here, the trait std::is_pod cannot be used because it is deprecated
24// in C++20.
